Thank you for the simplified code. Removing instances of PgenT worked.

cost_genvar, sum(
                    Pgen[i, j] * cov[i, k] * Pgen[k, j]
                    for i in bus_key for j in scenarios for k in bus_key
                 )

Here, the above product will simply square all the terms of the matrix Pgen. How to achieve the following

transpose (Pgen)*cov*Pgen
